Adenocarcinoma and squamous cell carcinoma are the most common types of esophageal cancer with a constant tendency to increase the incidence of growth on the background of the high mortality, which makes particularly the development of new biomarkers that complement and improve the early diagnosis of this disease. Despite the impressive number of studies in routine clinical practice is used only marker of esophageal cancer - ERBB2/HER2 status. This review summarizes data on the identified epigenetic markers of the aberrant methylation of the genome, which may be useful for early detection of esophageal cancer, prognosis estimation and / or prediction of response to treatment. The development of new high-tech genome-wide screening, such as beadarray and immunoprecipitation sequencing method used for the wideband genotyping, but for the analysis of transcriptome and metilom, provides a comprehensive picture of genetic and epigenetic changes during tumorigenesis. Note the need to verify the most biomarkers on large representative samples for the development of valid diagnostic panels, suitable for large-scale screening of risk groups.
腺癌和鳞状细胞癌是食管癌最常见的类型,在高死亡率的背景下其发病率呈持续上升趋势,这使得开发能够补充并改善该疾病早期诊断的新型生物标志物尤为重要。尽管有大量研究,但在常规临床实践中仅使用食管癌标志物——ERBB2/HER2状态。本综述总结了已确定的基因组异常甲基化表观遗传标志物的数据,这些标志物可能有助于食管癌的早期检测、预后评估和/或治疗反应预测。新的高科技全基因组筛查技术的发展,如用于宽带基因分型的微珠阵列和免疫沉淀测序方法,以及用于转录组和甲基化组分析的技术,为肿瘤发生过程中的遗传和表观遗传变化提供了全面的图景。需要注意的是,为了开发适用于大规模风险人群筛查的有效诊断面板,需在具有代表性的大样本上验证大多数生物标志物。
